MKS Inc. (NASDAQ: MKS), a global provider of enabling technologies that transform our world, today announced that its strategic brands Atotech, offering process chemicals, equipment, software and services, and ESI, providing laser systems, will showcase advanced manufacturing solutions for printed circuit boards (PCBs) and package substrates at TPCA Show 2026. The event will take place at the TaiNEX Center in Taipei, Taiwan, from October 20 to 22, 2026.

Enabling Next-Generation Electronics Manufacturing

The next phase of PCB manufacturing is defined by more than just design capability; it is also defined by the ability to reproduce advanced structures in large quantities with a stable yield and reliable performance. As high-layer-count multilayer and HDI PCBs transition to finer features, thinner dielectrics, and tighter assembly margins, achieving manufacturing consistency becomes paramount. In these circumstances, surface condition, seed layer and copper deposit quality, as well as final finish stability directly affect production yield and downstream performance.

As AI and HPC architectures increase interconnect density, bandwidth, and power delivery demands, PCB manufacturers must supply more advanced high-layer-count multilayers, HDI, substrate-like PCBs, and package substrates that meet tighter consistency requirements. In that environment, manufacturing becomes a determining factor in whether next-generation interconnect structures can be produced with acceptable yield, reliability, and assembly performance.

At TPCA Show 2026, MKS will present integrated surface treatment, laser processing, metallization, plating and final finishing chemicals and systems technologies for high-density PCBs, advanced package substrates, optical modules and next-generation packaging architectures.

This innovative approach results in improved yields, enhanced productivity, and superior performance - all without production interruptions.

"As AI, high-performance computing, and advanced packaging reshape the electronics industry, the challenge is no longer simply creating smaller features or denser interconnects, but manufacturing increasingly sophisticated structures reliably, consistently, and at scale. Industry leadership depends not only on design innovation, but on controlling every critical interface across surface preparation, metallization, copper deposition, and finishing. As the boundaries between semiconductors, substrates, packaging, and PCBs blur, the reliability and efficiency of tomorrow's AI infrastructure will increasingly depend on an integrated approach that optimizes materials, chemistry, equipment, and process control as a complete manufacturing ecosystem."
